my concern is for ak47 steel mags, glock 19 mags, ruger 10/22 25 round mags. i rather keep them all loaded in case i need them quickly. my ak47 mags are loaded since 1999 with one less round. i never had a malfunction so far. springs seem normal. i can feel the difference in my older glock mags but they never malfunctioned yet. they been loaded for 5 years. the new springs are out of stock of course. i bought 2 used mossberg 500 12 ga and the mag springs where very weak but still functioned. i replaced those. am i doing this right?
